Laravel: Eager loading duplication - laravel-4

Question

I'm trying to set up eager loading to prevent N+1 queries, but I'm finding that I have to duplicate some eager loads in order to get laravel to use the 'eager loaded' data. Duplicating the eager loads of course results in duplicated queries.
This is my load call:
$provider->load('ads.gallery.images', 'ads.thumbnail', 'ads.user', 'ads.provider.values.field', 'values.field', 'galleries.images');
A provider is a polymorphic subtype of a user. This is for a user profile page, which displays the user values list, as well as a list of all their ads. The ad display is a sub-view that's reused across the site and has a tab that displays the user values list as well. Yes it's redundant on this page, but that's how the site is designed.
I would expect laravel to reuse the already-loaded values.field list when the sub-view accesses it, but it doesn't, so I had to add ads.provider.values.field to the list, which duplicated the queries:
select `provider_field_values`.*, `provider_values`.`user_id` as `pivot_user_id`, `provider_values`.`value_id` as `pivot_value_id` from `provider_field_values` inner join `provider_values` on `provider_field_values`.`id` = `provider_values`.`value_id` where `provider_values`.`user_id` in ('3')
select * from `provider_fields` where `provider_fields`.`id` in ('1', '2', '3')
select `provider_field_values`.*, `provider_values`.`user_id` as `pivot_user_id`, `provider_values`.`value_id` as `pivot_value_id` from `provider_field_values` inner join `provider_values` on `provider_field_values`.`id` = `provider_values`.`value_id` where `provider_values`.`user_id` in ('3')
select * from `provider_fields` where `provider_fields`.`id` in ('1', '2', '3')
Is there any way I can eliminate this duplication? I'm not sure if the issue is in how the views access the data or if it's in the controller. I can add snippets of the view code if needed.
Edit: Model relationships:
//Provider model
public function values()
{
return $this->belongsToMany('ProviderFieldValue', 'provider_values', 'user_id', 'value_id');
}
//ProviderField model
public function fieldValues()
{
return $this->hasMany('ProviderFieldValue', 'field_id');
}
//ProviderFieldvalue model
public function field()
{
return $this->belongsTo('ProviderField');
}
//ProviderValue model (this is a pivot table)
public function provider()
{
return $this->belongsTo('Provider');
}
public function fieldValue()
{
return $this->belongsTo('ProviderFieldValue');
}
